Tb all wh0m it may concern:

Be it known that we, JOHN F. DODGE and HORACE' E. DODGE, citizens of the United.

ments in Trucks 'or Stands Used in Assembling Motors, of which the following-is a clear, full, and exact description. I

I This invention relates to trucks or stands adapted to be used in assembling motors,

such for instance as are used in driving an automobile. Among'the objects of'the invention are the provision of means whereby the assembling'of the various parts attached to the motor is not interfered with the provision of means for temporarily supporting the cylinder casting of a motor until the same is firmly "secured in position; the provision of improved means for clamping the cylinder. casting-in position; the provision of a swiveling arrangement which permits the motor to be rotated about a horizontal axis and to be locked in any one of a plurality of different positions; and the provision of means enabling the stand or truck to be elevated off of its wheels so that it will remain stationary while the motor is being .iasseinbled. Other objects are to provide a simple, practical and efficient stand or truck for facilitating the assembling of the parts of a motor.

These being among the objects of the present invention, the same consists of certain features of construction and'combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawings illustrating a suitable embodiment of the invention having the above and other objects in view, in which drawings Figure 1 is a side elevation of a stand ortruck according to the. present invention, the same showing in dotted lines the parts of a motor in process of being assembled; Fig. 2 is a plan of the stand or truck; Fig. 3 is a vertical centralsecti'on on the line 33 Fig. 2; p

Fig. 4 is aplan of the base of the stand or truck with its concomitant parts 3' Fig. 5 is a front elevation of the" yoke and clamping portions of the device;

showing the construction of-one of -the clamping devices; i

Referring to Figs. 1 to 1 inclus ve, the

base lO'of the stand or truck is provided at each end with apair of wheels [such as 11, 12, whereby the stand or truck is adapted to be wheeled from place to place. Intermediately of one side of said base thereis located an upwardly extendingsupport 13.

upon the upper end ofwhich there is secured as by means of bolts 14 an auxiliary supporting member 15, which is provided with a horizontal hub 16 having a bearing for a shaft or swivel 17, which carries at its front end a head or. disk 18 which backs up against a relatively large flat bearing surface 15". Said head or disk is provided preferably with four equidistant holes a519, which are arranged around the axis of said head and are preferably reinforced as by bushings or thimbles 20. The head 18 and the parts supported thereby and to be describedlater, are adapted to be set in various angular positions with respect to the axis of the swivel 17, through the medium of a locking bolt 21 which is guided in a bore 22 in the supporting member 16 and which is parallel with the swivel 17. Suitable means'are provided. for retracting the said bolt against the projecting action of a spring 31, such means preferably comprising an angle lever or bell crank 22 which is pivoted to the supporting member 13 at '23 and the upper end of which is connected by pin and slot connection-at 24 with said bolt. Said lever has a downturned end 25 which by means of a downwardly extending rod 26 is pivotally connected at 27 with a bolt retracting lever 28 which is pivoted intermediately of the base 10 at 29. said lever having at its outer end at one side of said truck a treadle 30. Preferably the said lever extends atits outer end through an treadle is released the spring 31 will project the bolt into the registering opening 19 in the head 18, so that said head may be secured in any desired rotated position provided by the plurality of openings 19.

The rotary head 18 carries a yoke 35 shown clearly in Figs. 1. 2, 3 and 5, and the arms or forks 36 of said voke are preferably 1nclined upwardly from the horizontal, so that when a cylinder casting such as is secured in the opening or recess of said yoke, the parts of the motor will be supported in the most favorable position for assemblingthem. There extends from said yoke midway between'its arms inclined supporting lugs 37, (10'. 61, the function of which is to enter the spaces between the cylinder barrels of the cylinder casting, below the water jacket. and

to prevent the same from slipping down while the casting is. being secured rigidly inposition. Said yoke is thus provided with a formed seat 'on which said casting rests. Each of the arms of said yoke carries clamping means, further illustrated in Fig. 7. and which preferably comprises a clamping arm or finger 38. which is adapted to be moved into or out of a recess 39 in said arm, while the inner 'end of said clamping arm or piece 3Sis pivoted to the yoke arm at 40. at a distance from the end of said yoke arm, so that the outer end of the clamp is adapted to swing for a suitable distance about the pivot l0. There will'thercfore be provided opposing clamping devices on the yoke adapted to be set and fixed rigidly upon the cylinder casting. as indicated in dotted lines in Fig. 7. To this-end each clamp 88 is adapted to be set in out 'ard position by means of a bearing screw l1 which engages a screwthreaded opening in the corresponding yoke arm. its inner end bearing against the back ofthe clamp, while its outer end is provided with a hand-lever 42. Said clamps 38 need have but a slight backward movement relative to the formed seat of the yoke 35, so that the cylinder casting can beseated in said yoke andbe then clamped by a slight forward movement of said clamps. The opposing faces of the arms of the yoke have a contour as at 43 which corresponds to the contour of the surface of the cylinder casting to be clamped while the opposing faces of the clamps also have a contour as at 4:4: to correspond with the surfaces of said casting to be engaged by the clamps. It will be seen that when the cylinder casting45 is clamped in position. it will be inclined with respect to the vertical axis of the truck and will be in a favorable position for, assembling the other parts of the motor thereupon. This inclined position of the motor is indicated in dotted lines in Fig. 1.

As shown more clearly in Figs. 2, 3, l, 8 and 9, the stand or truck is provided with means for lifting one of its wheeled ends from off the supporting surface for the device, so that the same will be held stationary. Such means preferably involve the use of a sort of jack and comprise a lifting member 46, which is guided through the base 10 0f the truck at 47, at a point intermediately between the wheels at one end of the truck. Said lifting member extends upwardly through the base 10 and its upper end is pivoted at 4:8 to a power lever 49 which is pivoted at 50 ,to a bracket 51 secured to the truck base. Said lever l9 extends outwardly beyond one side of the truck and is provided with a treadle 52, so that by pressing the foot upon the latter, said lever will act upon the corresponding end of the truck so as to lift the same, upon the pivot 48 as a fulcrum. This action compresses a preferably leaf spring 53 which acts on the lifting lever 49 at a point between the truck base and said lever, and when the depression action 'of lever 49 is relieved, said spring acts to restore the parts to normal position. In-order to' lock the lever 19 in its depressed position. a suitable latch may be provided,- said latch being pivoted to the truck base at 56 and having a nose or h1g5? adapted to engage over and hold the lever depressed. while the lower end of said latch is provided with an arm 58 adapted to receive the pressure of the foot so as to unlatch said lever. and to oppose the tension of a spring 59 connected with the truck base and latch and which acts to automatically latch the said lever down when it is moved to a point below the nose 5? of the latch.

It is obviousthat the invention is. susceptible of modification as parts may be omitted, added and substituted without departing from the spirit and scope of the invention as claimed.
